Michael "Mikey" Klebitz is an unseen character in The Lost and Damned.
Michael is the older brother of Johnny Klebitz. Michael and Billy Grey, the President of the Alderney chapter of The Lost MC motorcycle club, met when they were teenagers (Michael being 15 and Billy 13) and it is implied that this is how Johnny, who would have been 10 at the time, met Billy as well.
By 2008, Michael is a Captain in the U.S. Army or the U.S. Marine Corps, serving in Iraq and Afghanistan.
Michael e-mails Johnny during the course of The Lost and Damned. Michael appears to be a law abiding citizen, as he criticizes Johnny for his biker lifestyle and criminal activities, though Johnny responds by claiming he "knows what he is fighting for". Despite their opposing lifestyles, Michael and Johnny appear to have a close relationship.
